>> that's madness. >> maybe so, but it's not half as mad as the idea that brought us to this point. >> is there such a thing as a higher dimension, a parallel universe where otherworldly things can happen? ah. over the years, artists, writers, and filmmakers have tried to answer that question, creating some dazzling works of science fiction in the process. but are the higher dimensions we see in sci-fi really fiction? meet maggie, scientist by day and sci-fi fanatic by night. maggie's watching a 1950s film about scientists who invent a device that catapults them into the fourth dimension, where they can walk through walls and read minds. like the rest of us, maggie lives in a three-dimensional world. but she also appears to have an interest in alternate dimensions. in 1940, master sci-fi author robert heinlein wrote the short story "and he built a crooked house." in the story, our hero builds his home from an unfolded four-dimensional hypercube. when an earthquake strikes, the house folds up, creating the world's first four-dimensional house, where occupants can look down a hallway
and conservative jews will, if i could use a very crass term, hold their part of the market. they'll decline relatively simply because of their great growth of black protestants and hispanics, some catholics, some protestants. but there aren't very big cohort moves. the people who are now moderate and liberal and black protestants are not in the surge towards fundamentalism. hard core fundamentalism, i don't think has as much future as moderate evangelicals and the pentecostals. i think that's where the future is. it's pretty hard to stay hardcore fundamentalist in america. there are so many lures out there and to build rather thick walls is frustrating. it will remain around, but i would watch much more for the exuberant groups black pentecostal, white pentecostal and moderate evangelical. [interviewer:] okay, one of the difficulties people come uwith when we talk about religious diversity and a classroom religious pluralism there's a tendency to say, "well, if you study all the religions, you water down your own religion." is there a way that a model or technique people might use, to cheri
of information, each corresponding to counting different things about the children. abstractly, in using the buttons, i've turned the children into a mathematical object, a set. and the fact that it can be a little easier to count buttons in a jar -- or count properties of a set of objects -- than it is to count kids running around the neighborhood is just the smallest of hints at the power of combinatorics. counting things, that's what combinatorics is all about. as an individual field of study, it's a relatively new one. and these days, with its strong connection to the world of computing, by providing insights into how to best organize and understand the power of the computer, it's incredibly important for modern technology. however, as cutting edge as the subject may be, its basic concerns go back to puzzles and problems from the earliest recorded evidence of mathematical thought. now, this is a facsimile of the rhind papyrus, copied around 1850 b.c. by the scribe ahmes from the now-lost text of an earlier dynasty. it was named after a scottish antiquarian, alexander henry rhind, who
round trip, blasting asteroids to do it safely. for us, viewing the game on a video screen, the asteroids spaceship appears to live on the surface of a two-dimensional plane. but actually, it could be "living" in other places, like the surface of a cylinder or even more exotic surfaces. that's where topology comes in, a branch of mathematics concerned with the study of spatial relationships that don't depend on measurement and is more concerned with concepts like "between" or "inside" and how things are connected. a topologist doesn't care that we bent the asteroid universe to better understand it. in fact, to a topologist nothing happened. the game's universe is still the same, it's just viewed from a different perspective. this looking at the world from a different perspective is at the core of topology, and today helps mathematicians get to the essence of many unusual puzzles. and it all started with seven bridges. in the early 18th century, one of the world's greatest mathematicians pondered a popular puzzle of his day. it was a puzzle about the town konigsberg, a town
. zeno of elea, who predated aristotle, wrote a series of paradoxes that still give us pause today. one of the best known tells the story of achilles and the tortoise and their race. achilles is such a fast runner, he gives the tortoise a head start. they each run at constant speeds: achilles very fast, the tortoise very slow. after a finite amount of time, achilles gets to where the tortoise started, but the tortoise will have moved on. it takes achilles a finite amount of time to get to the tortoise's next spot, but by the time he arrives, the tortoise will have moved on from there as well. and so on, and so on, over and over again, ad infinitum. despite what our senses tell us, zeno is telling us that achilles will never catch the tortoise. zeno's paradoxes were a big problem for the greek philosophers, and they did just about everything they could to avoid confronting the infinite because they based their arithmetic and their entire worldview on something much more tangible: geometry. their notion of the mathematical and the physical was intimately linked to the practice of measurin
around us that seems bent on our creating our own demise? our sojourn through the wide, cool halls of the egyptian museum in cairo dramatically reinforces our three interrelated introductory class themes. rites of passage - in this case death - generate boundary questions - "where do i go when i die?" which is a pervasive human preoccupation from our most ancient civilizations up to the present. if nothing else, our mortality is the commonality that binds humanity together, and forces us to formulate religious answers to the sometimes overwhelming demands of our shared existence. faced with death, as are we all, the ancient egyptian pharaohs responded with unparalleled creative energy in their quest for immortality - from the magnificent statuary, elaborate burial masks, to the golden sarcophagus from tutankhamen's tomb, the visitor is struck by the egyptian response to death. of course, for most people, the pyramids of giza are ancient egypt. through the burial tombs for three pharaohs - a father, son, grandson trio who reigned during the 26th century before the common era - an eg
i guess we could use it - not lying, not cheating, not stealing... they say chastity, but we can get back to that one later - i think they're talking about moderation there. and in other words - let me give you a modern spin on that, just real quickly, on those kinds of things. if you think of not stealing, and not killing and these kinds of things as prohibitions, i don't think you've even begun to make the ethical understanding. and i like to think of a very common term in the psychological world as manipulation. if you're a person that's given to manipulating other people, that's when you're in- that you look at life like "i'm the center, and anything i can get for myself is okay." once you're there, then you can steal, you can cheat. cheating amazes me, because some say that 90 percent of students in college cheat. you can only cheat if you are in that mode that says you're the center of the universe and you can get something for yourself. so all these prohibitions actually come out of wrong mind set to begin with. yeah, go ahead, janet. >> and this is where the sexual misconduct
, where we replay and reinterpret stories of america, as eli wallach recounts for us in "the western." (clint eastwood) he's another person adrift on the great west's landscape. that's always been part of the fun of the game is that lone figure on this huge landscape. and what's it like to be out there? it's another world out there. (clint eastwood) maybe he was just somebody who drifted along, happened by, and maybe he was asked for. it's that fantasy of a guy solving the problem himself. he isn't picking up and dialing 911 or other aid. through his own ingenuity, he's working out the situation. if he doesn't, he doesn't exist. you don't like our company? what's the matter with you? i'm speaking to you. (gunshots) (john sturges) everybody would like to be the fellow that says, i'll do it. i'm the one that can do it. everybody else tries, but turn to me, i can solve it for you. they want the magic touch, they want to be the legend. you liked good westerns and you may not have known why, but they were wonderful to watch. (budd boetticher) and it's very romantic. if movies could be a r
-in, both equally astute. one is brother mark, who used to be, i believe, a dentist or some kind of professional field, and he gave that up in order to go to this monastery, where he lives his life, and a life of meditation and prayer and connection with god. bishop thomas, on the other hand, is a major bishop in the coptic faith in egypt, but listen particularly, because we've had barbara's beautiful sahara - once again, we're getting too many synchronicities in this class. we have this book - from the library, folks; that's why you can't see the front on it - but we have this book about the sahara - we'll, we're going to the sahara; i forgot about that. yeah, we're going back to the sahara, and listen to what life would be like there. and so, if we could, let's go to st. macarius monastery in the deserts outside of cairo. >> the word monk , or monastery, monasticism, from mono - mono means single, one-say but one. here is all the monastic ones - mono, monk, monastic - they lived as hermits alone in the desert. now we live in a community together, so we built a wall all around t

smokes, a dropped kerchief! that hasn't been used since lily langsley. you'll have to pick it up yourself, madame. it's a shame that he'll never see it. oh, you don't like her either? well, what are you gonna do about it? oh, you just can't stand it anymore, you're leaving. these women don't give you a moment's peace, do they? go soak your head and see if i care! introduce the man and the woman in the beginning of the movie, and then you complicate it for the next 60, 70 minutes, and you know they're gonna get together at the end, but it's fun to watch how they keep missing each other. it's kind of a tough thing, because if you say, "here's a romantic comedy, and i'm trying to keep the tension alive," except the audience comes in, they know who's in it, so they know they're gonna get together. so you always throw in obstacles to keep people apart. (robert zemeckis) the stakes in the story kept getting higher, the reaction the audience has watching these films is "my god, how are they ever gonna get together?" (amy heckerling) you're walking a fine line between having the reason, and with
